SHEET-DELIVERY MECHANISM FOR PRlNTlNG PRESSES.

SPECIFICATION forming part of Letters Patent No. 417,884, dated December24, 1889.

Application filed July 19, 1888. Serial No. 280,385. (No model.)

To a/ZZ whom it may concern:

Be it known that 1, JOHN H. REYNOLDS, a citizen of the United States,residing at Chicago, county of Cook, and State of Illinois,

have invented certain new and useful Improvements in Sheet-DeliveringMechanism for Printing-Presses, which are fully set forth in thefollowing specification, reference being had to the accompanyingdrawings, forming a to part thereof.

In the drawings, Figure 1 is a right side elevation showing the cylinderof a printingpress and portion of the frame in connection with mydelivering mechanism. Fig. 2 is a front elevation of the reel-andportion of the frame and gripping and discharging fingers of thedelivering mechanism. Fig. 3 is a left side detail elevation of thedelivering mechanism, with the delivery-table shown in section. Fig. 4is a similar elevation showing the delivering mechanism at a differentpoint of its action and the delivery-table adjusted to a differentposition. Fig. 5 is a detail of the table gripper and discharger indifferent position relatively to the roll from that shown in Fig. 4.Fig. 6 is a front elevation of the parts shown in Fig. 3,showing,'however, only one of the gripping and discharging fingers, theremainder of the mechanism being broken 0 away. Fig. 7 is a perspectiveof a lever arm in the rock-shaft, which carries the leverfingers.

A is the imprcssion-cylinder; B, a portion of the frame comprising thefeeding-table.

3 5 C is the delivering-reel, which is journaled on the frame in theusual manner and in the usual position with respect to the cylinder A.

D is a fixed portion of the delivery-table, containing supports for thedelivering mech- 4o anism other than the reel. D,D and D are furthersections of the delivery-table hinged together, the first being hingedto the fixed section D.

A represents the grippers on the cylinder,

5 and C the grippers on the reel, which cooperate in the usual manner,whereby the reel takes the paper from the cylinder, seizing it by meansof the grippers C, which are fixed upon the roek shaft C and areoperated by the cam c, secured to the frame and encircling thereel-shaft c, said cam en gaging the roll 0 at the end of the leverarm Cand thereby rocking the shaft C at proper time to cause the grippers toengage and release the sheet, as hereinafter specifically explained.

At the opposite end of the shaft 0 from that at which is located the camC there is secured to the reel another cam E, which op crates thedelivering mechanism, which I will now describe. Upon the fixed sectionD of the delivery-table there are provided two brackets d, one at eachside of the table, and in said brackets there is journaled therock-shaft fiwhich is provided with grippers F, located at intervalsthroughout the length of the shaft, being preferably one for each ringof the reel C. To said r0ck-shaft at the end corresponding to that endof the shaft 0 at which is secured the cam E there is secured theangle-lever G, one portion of said lever extending horizontally in thedirection of delivery and the other portion extending up from said anglevertically, and being provided at its upper end with a cam-roll g, whichcontacts with the cam E. At the angle of the lever there is connectedthe plunger-rod G, which extends downward through the sect-ion D of thereceiving-table, in which there is formed a socket (l, somewhat largerthan the plunger G, so that there is room within it around said plungerfor the coiled spring giwhich is stopped at one end against the bottomof the socket and at the other end against the eye g, by which theplunger is connected to the lever G. In the brackets d there is alsojournaled a rock-shaft II, which extends across the whole breadth of thedelivery-table and is provided with the straight fingers 1-1. Thesefingers I will hereinafter o refer to as the delivery-fingers, as theirpurpose is to discharge the paper onto the delivery-table. To saidrock-shaft H, just outside its bearing in the bracket at the end at I,which is located the cam E, there is secured 5 the lever-arm J, which iskeyed onto saidshaft so that it projects close alongside of the lever G.It has the stud j projecting into the slot J, formed in the horizontalportion of said lever G, said slot extending horizontally for a veryshort distance only to allow for certain movementof the stud j therein.The

ICC

fixed section D of the delivery-table has a slot extending transverselyacross the width of the machine-2'. 6., lengthwise of the section D-andin said slot are secured the gripping-posts K, which are provided withthe shoulders is above the delivery-table and with the beveled washers Kbelow said table, and at their ends are screw-threaded and provided withthe clamp-screws K whereby they are adapted to be adjustably securedanywherein the length of said slot. The grippers F are also adjustablelongitudinally on the shaft f, and are designed to be adjusted so thattheir points will rest upon the upper ends of the gripping-posts K,respectively. The delivering-fingers H are also adjustable on the shaftH, and are designed to be set thereon so that they shall open closealongside of the posts K, respectively, and play past them in themovement which they re ceive by means of the mechanism described.

The operation of this mechanism is as follows: The sheet carried by thecylinderA and tion is performed precisely as in well-known deliveringdevices for printing-presses and forms no part of my invention, exceptin so far as the cam C is slightly changed in form, its raised portionnot being extended so far as in the ordinary construction, in order toadapt it to co-operate with my delivering mechanism. The paper, beingthus seized by the grippers of the reel, is carried around on the reeluntil the several parts of the mechanism reach the position shownin Fig.5. The position illustrated in this figure is that at which thedepression 6 in the cam E has reached the cam-roll on the end of thelever G and permitted the spring g to force said lever upward to theextent of said depression. This movement of the lever rocks the shaft fand throws back the points of the grippers F,

lifting them oif from the ends of. the grippin g-posts K, respectively.At the same time the said lever G, by its slot J engaging the stud j,rocks the shaft H, causing the dis charging-fingers H to tip forwardpast the posts K, the position of the parts being, therefore, as shownin said figure. tinues its revolution and commences to force thecam-roll on the end of the lever G out of the depression 6, the movementof the grippers F and 'discharging-fingers H is reversed,

the discharge-fingers receding past the post K As the reel con- Whilethis movement is occur- 1 ring, however, the reel by its revolution iscausing its grippers to carry the edge of the paper still in their claspin against the receding discharge-fingers H and under the descendinggrippers F, and the cam C has the their grasp, leaving it, therefore,stoppedagainst the discharge-fingers H and grasped in the grippers Fupon the posts K. The roll L upon the side of the reel has up to thistime been holding the paper on the reel. As the reel now continues torevolve, the end of the paper no longer being carried by it, but held onthe posts K by the grippers F, the other end of the paper is rolled offby the reel from under the roller L and falls down upon thedelivery-table D D D D and when the reel, having completed anotherrevolution, brings the notch e of the cam E again around to the cam-rollupon the end of the lever G, the movement of the parts actuated by saidlever being repeated precisely as above described, the outward movementof the discharge-fingers H, which in its first occurrence abovedescribed effected no result, now discharges the paper free of the postsK and causes the end which has been grasped thereon to fall onto thedelivery-table. Thus two complete revolutions of the reel effect thecomplete discharge of the paper on the table. It will be observed thatthe eccentric portion of the cam O, by means of which the movement ofthe grippers G is produced, must be located at such point in thecircumference of the cam that it will cause the grippers O to releasethe paper at the point where it should be seized by the grippers F. Thispoint is so near the point at which the grippers C would necessarily beopened in order that they might be closed upon the paper to take it fromthe cylinder that the same enlargement serves both purposes by beingslightly extended.

In order that the paper falling from the reel onto the delivery-tablemay not double up or collapse, instead of falling out at full length, Iconstruct said table so that its in clination may be varied to increasethe distance that the end of the paper will fall before it reaches thetable to correspond somewhat with the length of the sheet and theflexibility of the paper. Thus, if the sheet is a short one, the tablemay be set up as nearly horizontally as it is ever desirable, theinclination of the fixed section D being designed to show about thenearest approach to a horizontal position which is desirable. If thesheet is long, and especially if it is light and very flexible, I dropthe outer end of the table, so that the sheet, however light, Willunroll its full length, and if it were necessary the table might bedropped almost to a vertical position at the outer end, so that the endof the sheet could not fail to fall out over it. The best result inrespect to this movement of the paper, especially with large sheets, isattained by having the table set at different inclinations at differentparts of its length, the inclination increasing-that is, the tablebecoming steepertoward the fartheror outer side, and for this purpose Iconstruct the delivery-table in the several sections D D D D saidsections being hinged together, so that their inclination may besuccessively increased.

In order to support the table in any position to which it may beadjusted, I provide in the outer upright edge of the legs B of the frameB a vertical slot Z), in which the supporting link or clip N is made toslide, said clip being adapted to be secured at any desired positiontherein by the clamp-screw N. This clip may also be set at an angle withrespect to the slot, being turned on the clamp-screw. The lower end ofthe clip has the slot N in which the edge of the section D of thedelivery-table is received, and a clamp-screw N is provided to fastenthe clip to the edge of said section D The section I) is hinged to thesection D beyond the clip N and extends beyond the legs B, and isprovided with the link N pivoted to the under side of it, and having aslot of, which runs on the clamp-screw N, which is screwed into the leg,so that the section D can be raised and lowered, swinging on the hingewhich joins it to the section D Thus each of the sections of thedelivery-table may have a different inclination increasing from theinner to the outer,'or they may all or any two consecutive sections havethe same inclination.

In order to cause the sheets to be delivered in a uniform pilenotwithstanding the slope of the table and the fact that they fallfreely thereonto, I provide the stop-gage M, which is secured to theouter section D and adj ustable toward and from the delivery mechanismaccording to the length of the sheets, and in case of sheets too shortto be delivered with their outer edge so far out as the section D", thetwo sections D D being set at the same inclination, the gage may beadjusted inward toward the delivery mechanism and located thereby on thesection D the arm M of said gage being long enough to permit it to bethus located while still secured on the section D The paper fallingfreely in the manner described would be liable to move sidewise,floating on the arm as it falls, and to prevent irregular delivery inrespect to the said edges of the sheets, I provide the side gages P andQ, one at. each side, which are adj ustable laterally in any convenientmanner and are designed to be set so that the sheets can fall freelybetween them, but without any considerable play, whereby the pile ofsheets as delivered will be substantially uniform on all its edges.

In operating with short sheets, especially of stiff paper or card, thegrippers F are not always necessary, and all the mechanism. connectedwith the levers G may in that case be dispensed with, except that a stopsuch as is afforded by the fingers H might be pro vided.

I claim 1. In a printing-press, in combination with the delivering-reeland the grippers thereon, the gripper-opening cam located in position toopen the grippers while they are on the under side of the reel, and thedelivery-table commencing under and receiving the sheet directly fromthe reel and inclined downward therefrom, substantially as set forth.

2. In combination with the reel, the cam E thereon, thereceiving-table,and the grippershaft f, having its bearings fixed withrespect to the table, said shaft having the lever-arm G and the grippersF, suitable fixed counterparts, as the posts K, to co-operate with thegrippers to ho d the paper, the shaft 'I-I, journaled on the table andhaving the dischargingfingers H, and the lever-arm J, which is engagedby the lever G, whereby the discharging-fingers are tipped forward todischarge the paper when the table-grippers are opened to release it,substantially as set forth.

3. In a printing-press, in combination with the reel, the delivery-tableextending under the reel, the grippers and dischargers, both havingtheir shafts journaled in bearings fixed with respect to the table, anda cam on the reel, which operates them to open the grippers and tipforward the discharge-fingers simultaneously, substantially as setforth.

4. In combination, substantially as set forth, the table-grippers andthe dischargingfingers, and the mechanism, substantially as set forth,which operates them simultaneously to open and close the grippers byimmediately successive movements and tip the dischargers forward andthen backward by movements respectively simultaneous with the movementsof the grippers, whereby the grippers seize the paper if presented tothem during such movements, and at the next repetition of such movementsthe dischargers eject it without change in the movement for the twopurposes.

5. In a printing-press, in combination with the delivering-reel, a tablelocated partly thereund er and inclined downward therefrom, such tablebeing formed in successive sections whose inclination is adjustableseparately, whereby said sections may be set at steeper inclinationssuccessively from the receiving to the discharge side, substantially asset forth.

6. In a printing-press, in combination with the delivering-reel and thedelivery-table located partly thereunder and inclined downwardtherefrom, said table being formed in successive sections hingedtogether, the clip N, adjustable vertically on the frame and pro videdwith means for clamping it to the edge of the third section of thetable, and adjustable also in an are about the point of its connectionto the frame, whereby it serves to adjust the inclination of the secondand third sections, substantially as set forth.

7. In a printing-press, in combination with the delivering-reel, thedelivery-table secured thereunder and inclined downward therefrom, theside gages P and Q ext-ending parallel with the plane of rotation of thereel and adj ustable laterally in the direction of the axis of the reel,substantially as set forth.

In testimony whereof I have set my hand, in 10 the presence of twoWitnesses, at Chicago,this 2d day of July, 1888.
